I-MCCB: isilinganiso somkhawulo womkhawulo wokwephuka kwesekethe emfushane

Uma ukhethai-circuit breaker yekesi ebunjiwe (I-MCCB) ohlelweni lwakho lukagesi, udinga ukunaka izici eziningana ezibalulekile. Enye yalezi zimfanelo amandla okuphula i-short circuit alinganisiwe. Le mfanelo ibalulekile ekuqinisekiseni ukuphepha nokuthembeka kwezinhlelo zikagesi, futhi kubalulekile ukuqonda ukubaluleka kwayo lapho ukhetha i-MCCB.

Umthamo wokuphuka kwesekethe esifushane olinganiselwe ubhekisela ezingeni eliphezulu lapho i-circuit breaker ingaphula khona ngokuphephile ugesi wesekethe esifushane ngaphansi kwezimo ezithile. Lesi sici sibalulekile ekuvikeleni izinhlelo zikagesi emiphumeleni engaba yingozi yamaphutha esekethe esifushane. Ngemva kwenqubo yokuhlola enqunyiwe, i-circuit breaker kumele ikwazi ukuqhubeka nokuthwala ugesi wayo olinganiselwe ngaphansi kwanoma yiziphi izimo. Lokhu kuqinisekisa ukuthi uhlelo lukagesi luhlala lusebenza ngisho noma kwenzeka ukwehluleka kwesekethe esifushane.

Ngaphezu komthamo wokuphuka kwesekethe esifushane olinganiselwe, umthamo wokuphuka kwesekethe esifushane osebenzayo olinganiselwe we-molded case circuit breaker kumele ucatshangelwe. Lokhu kubhekisela kumthamo wokuphuka ngaphansi kwezimo ezicacisiwe. Kufanele kuqashelwe ukuthi i-circuit breaker kumele iqhubeke nokuthwala ugesi wayo olinganiselwe ngemva kokulandela izinqubo zokuhlola ezicacisiwe. Lesi sici sibalulekile ekuqinisekiseni ukuthembeka nokuphepha kwesikhathi eside kwezinhlelo zikagesi.

Kuyaphawuleka ukuthi abakhiqizi abaningi be-circuit breaker basekhaya njengamanje bahlinzeka ngama-plastic case circuit breaker anamazinga ahlukene amakhono okuphula i-short-circuit yamandla afanayo alinganiswe ezingeni lohlaka. Lokhu kuvumela abasebenzisi ukuthi bakhethe i-circuit breaker ehlangabezana kangcono nezidingo zabo ezithile kanye nezidingo zabo. Uma ukhetha i-molded case circuit breaker, kubalulekile ukuqinisekisa ukuthi amandla okugcina e-short-circuit breaker ye-circuit breaker anele kumandla okugcina e-short-circuit alindelekile entanjeni kagesi. Lokhu kuqeda isidingo sokwengeza izinto zomshuwalense ngokwenziwa, okungaholela ekuchithekeni okungadingekile.

Inani lomthamo wokuphuka kwesekethe esifushane sokusebenza olinganiselwe lingahluka, kanti ama-circuit breaker amaningi ahlinzeka ngamakhono asukela ku-25% kuya ku-75% womthamo wokuphuka kwesekethe esifushane olinganiselwe. Amanye ama-circuit breaker ahlinzeka ngisho nangu-100% womthamo wokuphuka kwesekethe esifushane sokusebenza olinganiselwe. Kubalulekile ukucabangela la manani ngokucophelela lapho ukhetha i-MCCB ngoba athinta ngqo ukuthembeka nokusebenza kohlelo lukagesi.

Ngamafuphi, umthamo wokuphuka kwesekethe esifushane olinganiselwe uyisici esibalulekile okufanele sicatshangelwe ngokucophelela lapho ukhetha i-MCCB yesistimu yakho kagesi. Ngokuqonda ukubaluleka kwalesi sici kanye nomthelela waso ekuphepheni nasekuthembekeni kwesistimu kagesi, ungenza isinqumo esinolwazi lapho ukhetha i-MCCB ehlangabezana kangcono nezidingo zakho ezithile nezidingo zakho. Ngenxa yezinketho ezahlukahlukene ezitholakala kubakhiqizi be-circuit breaker basekhaya, kubalulekile ukuhlola ngokucophelela amakhono okuphuka kwesekethe esifushane e-MCCB ehlukene ukuqinisekisa ukuthi ukhetha inketho efanelana kahle nesistimu yakho kagesi.
